AUTOMATIC BOlLER-CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 423,943, dated March 25, 1890.

I Application filed October 1'7, 1889. Serial No. 327,823. (No model.) Y

To @ZZ whom it may concern:

Be it known that I, DAVID MYERS, a citizen ofthe United States, residing at North Manchester, in the county of Wabash and State of Indiana, have invented certain new and useful Improvements in Automatic Boiler- Cleaners; andI do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this speciiication, and to the letters of reference marked thereon.

This invention relates to cert-ain new and useful improvements in automatic boilercleaning apparatus of that class in which the foul water in the upper levels of the boiler is caused to pass out from the boiler and into a precipitator, where the heavier matters are collected and left, the purified water vreturning to the boiler.

It has for its object to improve upon prior devices of this character, providing` an improved form of skimmer, whereby better results are accomplished.

The novelty resides in the peculiar combinations and the construction, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the drawings, and then particularly1 pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which-- Figure 1 is a vertical section, with parts in side elevation and broken away, illustrating my improved apparatus in connection with a boiler. Fig. 2 is a side elevation of the skimmer removed and on an enlarged scale.

Referring now to the' details of the drawings by letter, A designates a portion of a boiler of known construction.

C is the precipitator or cylinder, suitably supported, as shown, at some point in proximity to theboiler. It is provided with a suitable blow-off or clean-out pipe and cock d at the bottom, as shown in Fig. l.

D is a tube suitably supported by the upper wall of the boiler and extending a distance within the boiler and upward a distance outside thereof, as shown in Fig. l. Attached to the top of the precipitator or cylinder C is a tube E. Extending downward through this tube and a distance within the cylinder is the pipe F, which at its lower end is provided with the branch pipes b-in this instance four in number, although the number may be varied, if desired. These bran'ch pipes are carried by a suitable collar c, designed to be detachably connected with the lower end of said pipe so it may be removed for the purpose of cleaning or for other causes. This pipe passes upward through the tube and has connected therewith a horizontal pipe CZ, provided at the junction of the two with a suitable regulating valve or cock e. This pipe cl communicates at its other end with the interior of the tube D, at the upper end thereof, suitable couplings being provided for the connection of these parts, as shown.

G is a pipe communicating with the upper end of the tube E, and extending horizontally for a short distance, thence upward to a point above the pipe CZ, thence horizontally parallel with the saidpipe d and above the same to a point over the upper end of the tube D,and then extending downward through the said tube, as shown in Fig. 1, to nearly the bottom of the boiler. A suitable regulating valve or cock f is provided in the said pipe G, as shown.

Upon the lower end of the tube D is a skimmer H, the construction of which can be best' seen from Fig 2. It consists of an inverted conical chamber, through the bottom of which the tube extends, as shown in Fig. 2, the lower end of the tube being provided with slots g and the disk or plate h, which is connected with the conical chamber and supported by means of the ribs or wings c', as

shown in Fig. 2.

The operation is similar to analogous devices of this character, and a description thereof is not deemed necessary.

The branch pipes l? are considered important, as they convey the sediment to the outer and cooler parts ot' the precipitator or cylinder and allow only the clear water topass up through the center of the tube E to the boiler. skimmer is also of importance. The wings serve to divide the scum, and the sloping sides of the body of the skimmer serve to guide the The peculiar construction of the.

foreign matters down to the apertures in the tube. The disk beneath the body serves also as a gatherer for the scum, catching what might not be gathered by the body itself.

What I claim as new isl. In a boiler-cleaner, the combination, with a precipitatin g-chamber, a pipe lead ing thereto from the boiler, and a pipe leading' therefrom to the boiler, of a skimmer within the boiler and branch pipes connected with the pipe within the precipitating-ehamber, substantially as and for the purpose speciiied.

2. In a boiler-cleaner, the combination, with a precipitating-chamber, a pipeleading thereto from the boiler, and a pipe leading there from to the boiler, of a skimmer within the boiler and branch pipes on the lower end of the pipe within the precipitatingfchamber and carried by a collar detachably connected with said pipe, substantially as described.

3. In a boiler-cleaner, the combi nation, with a precipitatingchamber, a pipeleading thereto from the boiler, and a pipe leading therefrom to the boiler, of a skimmer within the boiler and lia-ving a conical-shaped body with an apertured tube extending below the bottom of said body, substantially as shown and described.

4. In a boiler-cleaner, the combination, with a precipitating-cl1amber, a pipe leading thereto from the boiler, and a pipe leading therefrom to the boiler, of a skimmer within the boiler and having a conical body, a disk beneath said body, ribs connecting the disk and body, and an apertured tube extending below the bottom of the body above the disk, substantially as and for thepurpose specified.

5. As an improved article of manufacture for use in boiler-cleaners, a skimmer formed with a conical body, a disk beneath the body and connected thereto by :ribs or Wings, and an apertured tube extending through the bottoni of the body, substantially as herein shown and described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

DAVID MYERS.
